I started a raw food diet and intermittent fasting about one or two months ago.
I was on fruits at the beginning (kind of 80/10/10) but my body became very lean and I had to go back eating more vegetables, nuts and oil, and few cooked veges.

I am reading Shelton's book on fasting. He really says that long water fasting are the best to rejuvenate the body and cure all kind of diseases.
So, I am attempting to do a long water fast to detox my body efficiently. The problem is that I have a part time job only very few hours in the morning, but I think I cannot do it while fasting because I have too many detox symptoms (dizziness, tachycardia, bad taste in the month, and weakness in the muscles).

What should I do then?

Is really intermittent fasting the right way to reach a breatharian life style without trying to detox the body qt first?
